While analyzing a blood gas control sample, you notice a trending of several PCO₂ values above the 2 SD range over the last six control samples run. What corrective action would you consider at this time?
1) Check the function of the PCO₂ electrode.
2) Rerun the control sample a second time.
3) Repair or replace any failed components.

Option 1 suggests checking if the PCO₂ electrode is working correctly, which is a necessary step to take. Option 2 suggests rerunning the control sample to confirm the observations made, which is also essential. Option 3 suggests repairing or replacing the failed components, which might not be necessary at this stage. Therefore, options 1 and 2 are the best choices at this time. Option 3 can be considered later if the electrode is found to be faulty or if rerunning the control sample confirms the initial observations.
